No progress at all so far. According to the ticket there is a working
mingw port now:
http://hackage.haskell.org/trac/ghc/ticket/1884
There is apparently support for Win64 in libffi (not sure if this patch
has been merged or not):
http://gcc.gnu.org/ml/gcc-patches/2009-06/msg00782.html
So the main remaining difficulty would be implementing the Win64 C call
ABI in the native code generator.
